Costs relating to haulage and processing of materials have considerable impact upon economics of road construction. Hence material search is generally restricted to about 10km corridor centering on the road but materials found at this distance may not satisfy the required quality. Cinder gravels are most abundant materials found in tropical countries like Ethiopia especially in rift valley zones where there are active volcanoes. The main objective of the study was to investigating use of cinder gravels as base course material through blending with conventional base course material, CSA, and stabilization with cement. According to results of sieve analysis, ACV, flakiness index and CBR, 30% of CSA can be replaced by cinder gravels for use as GB1 material and for cement treated cinder gravels adding 6% and 8% cement make them suitable for use as CB2 and CB1 base course materials respectively, referring to their 14 day compressive strength as determined by UCS test while the mix with 10% cement satisfies US Army specification. Based on the results of the research, it is recommended that utilization of the locally available cinder gravels shall be given due consideration for upcoming road construction projects in the study area or in other locations with similar characteristics.
